what difference between "flush magento cache" , "flush cache storage" in magento's cache management? sometimes cache location (like "/tmp/") or service (like memcache) shared other applications. "flush magento cache" removes entries magento reliably tracks it's own. "flush cache storage" clears might affect other applications if they're using it. normally location "var/cache/" in magento's folder not shared after all. safe use either button. (rarely) entries not tagged or magento loses track of them , second button has effect on them. tend use second button when i'm having difficulty tracking down cause of problem.

i have following data model: camp -> campevent <- event. camp has campid , name associated it. event has eventid, name, start/end (dates). campevent has (campid,eventid)pk, campid fk, eventid fk. the tables used create domain model , domain service consumed client side on silverlight. i able display event's table in silverlight using grid. the grid has 2 template columns - 1 display checkbox, , display name of event. so problem somehow need check checkboxes when control goes in edit mode. i've noticed grid doesn't have ondatabound event, or doesn't have way of setting state of each checkbox checked other through binding. well, apparently in silverlight don't have luxury of messing around contents of gridviewrow. can, however, achieve changing underlying data source. in above scenario have control used creating instance of camp , associating 1 or many events. in sense control can either create or update "camp" object , re...

i have isp provider (telenet). provides via dhcp public ip there dsl modem. modem have rj45 cable connected 24 port switch. now in our local network: - switch port 1, have 1 voip phone - switch port 2, have voip phone each has default gateway 78.21.232.1 , subnet mask 255.255.240.0. different public ip such 78.21.235.x or 78.21.232.x series. question/confusion: when send packets our local network our local public ip's, traffic going isp default gateway? or straight inside our switch network? but saw many times gets packet loss in voip phone diagnostics. making me confused now. you've got several places more information packets go. first routing tables : $ ip route 192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.121 metric 1 169.254.0.0/16 dev eth0 scope link metric 1000 default via 192.168.0.1 dev eth0 proto static this shows interfaces ( virbr0 , eth0 ) us...

i addres of string assembler c, , need content of address. how it? google gives c++ examples reinterpret_cast, not working in c (i suppose). appreciate if note needed libs too, tenx #include <stdio.h> #include <stdlib.h> unsigned long const1(void); int main() { printf("const: %d\n", const1()); return 0; } if you've got address , know it's null terminated string, need treat string. printf("%s", (char*)alleged_string_address);
